Patent DE-2923025-A1 (DE)
Inventor: SCHACHER ROGER
IPC: H02P3/12
Filed: 1979-06-07
Abstract: The controlled rheostatic brake in which an exciter winding (2) and a brake resistor (3) are connected in series with an armature winding (1) is constructed such that a non-linear resistor (4.1 to 4.n) with voltage-limiting characteristic is connected parallel to the exciter winding (2). Expediently, the non-linear resistor (4.1 to 4.n) is formed by a plurality of silicon diodes connected in series, any number of which can be connected. The circuit arrangement can also be used for a multi-motor drive. The non-linear resistor (4.1 to 4.n) is connected parallel to the exciter winding of a machine, the other machines being constructed as separately excited machines. The advantage of this circuit arrangement lies in the fact that the braking force can be set with simple means, even in the region of the linear variation of the machine characteristic, with the aid of the non-linear resistor (4.1 to 4.n) connected in parallel. The circuit arrangement is intended in particular for electrical power units. <IMAGE>

Title: Control circuit for two antiparallel thyristor groups - has window discriminator determining magnitude and direction of stipulated current in three=phase bridge
Inventor: EMMERLING FRANK DIPL ING
IPC: H02P7/03
Filed: 1979-07-16
Abstract: The control circuit has a window discriminator to detect the magnitude and direction of the stipulated current. The discriminator receives two reference voltages and a value describing the stipulated current. The discriminator's output is connected to a bistable flip-flop to select the converter group needed for controlling the speed of the motor, and to operate a pulse disabling circuit to prevent switch pulses being passed to thyristors in the converter groups, and to operate a polarity reverser to fix the sign of the control voltage and actual current.
Patent DE-2931070-A1 (DE)
Title: Inverter with forced commutation employing gate-turn-off thyristors - has capacitor across each thyristor to suppress dangerous switch off transients
Inventor: SCHNEEVOGT HENNING DIPL ING
IPC: H03K17/0814
Filed: 1979-07-28
Abstract: The inverter supplies a resistive inductive load with power from a dc source. The transient suppression circuit reduces the losses and number of components required. In place of the conventional RC snubber circuit with a diode bypassing the resistor in the direction of current flow for charging the capacitor, a single capacitor only (Cs1-Cs6) is connected across each gate turn-off thyristor (T1-T6). Elimination of the diode permits both capacitors in an inverter bridge arm (Cs1,Cs4; etc.) to take part in each commutation. Therefore the value of capacitance for each unit can be reduced by 50 per cent. Also with this connection the stored energy in the capacitors is returned to the load when the next thyristor turns on. There is thus no power dissipation in resistors thereby increasing efficiency and reducing cooling requirements.

Title: Salt bath furnace electrodes - have cooling channels in specified location in horizontal part
Inventor: BISIK NIKOLAJ K
IPC: H05B3/03
Filed: 1979-08-23
Abstract: Salt bath furnace for the non-oxidising heat treatment of metallic workpieces has two horizontal electrodes near the furnace bottom which are cooled throughout their length. The width between the cooling channel and the surface facing the opposite electrode can vary from 1/16 to 3/4 of the electrode width and is proportional to the inter electrode gap. This keeps the electrode temp. below the temp. of the salt bath, e.g. boron trioxide with an admixture of sodium, potassium, lithium and zirconium oxides, and lengthens the service life of the electrodes, e.g. to 600 hr. at 1300 deg. C.

Output is enhanced, and the negative effect of ejection speed on solidity is reduced.
Patent DE-2940511-A1 (DE)
Title: Reactor safety system for heat-transfer medium - has openings in reactor chamber walls and spaced round periphery
Inventor: BUKRINSKIJ ANATOLIJ M
IPC: G21C9/012
Filed: 1979-10-05
Abstract: The reactor safety system limits the consequences of a fault connected with loss of the heat-transfer medium in a nuclear power plant, having a first chamber contg. a reactor and a sprinkler condensing the steam produced by the boiling of the medium on the occurrence of the fault. On rise of internal pressure due to the fault, air in the chamber escapes via wall openings into an intermediate chamber, and from there into a second chamber contg. a steam-condensing basin. The openings in the first chamber walls are immediately adjacent to the bottom of the chamber, and are spaced apart round the periphery for the maximum distance. Thus the max. quantity of air is expelled through the openings and into the condenser basin in the second chamber, irrespective of where the damage occurs in the reactor. The length of the passages leading to the second chamber is such that a water lock is formed in them, preventing reverse flow of air from the second chamber into the first, and generating a vacuum in the latter.

Title: Track coupling for electric model railway - uses plastics bed plates, metal rails and coupling tongues of spring-hard metal
IPC: A63H19/30
Filed: 1980-10-13
Abstract: The coupling elements are clamped beneath the track ends on the bedplates and form lock stops with the rail feet. The width of each coupling tongue corresponds to the width of the rail foot and width of the grooves. The locking grooves have the advantage that the snap action of the coupling, increases the frictional contact. The construction height between the centre of the coupling metal and rail foot, is optimally small. Track sections for model railways have sections which are normally too stiff about the horizontal axis across the direction of travel. This is overcome by making the elements of flexible metal spring plate, whose interlocking offers the best electrical conduction to carry the track current.
